Database-Driven Kubernetes Automation in 10 Minutes

A hands-on tutorial that walks users through:

1. Installing Lynq Operator with cert-manager
2. Setting up a MySQL database with sample tenant data
3. Creating a LynqHub to sync database rows
4. Defining a LynqForm template
5. Testing the full tenant lifecycle (add, deactivate, reactivate, update)

Duration: ~10 minutes Environment: Kubernetes (kubeadm 1-node)

1. Create an account on Killercoda
2. Fork/clone this repository

1. Go to Killercoda Creator
2. Connect your GitHub repository
3. Select the killercoda directory as the scenarios root
4. Publish the scenarios

Each scenario follows this structure:

scenario-name/
├── index.json      # Scenario configuration
├── intro.md        # Introduction page
├── step1.md        # Step 1
├── step2.md        # Step 2
├── ...
└── finish.md       # Completion page

{
  "title": "Scenario Title",
  "description": "Short description",
  "details": {
    "intro": { "text": "intro.md" },
    "steps": [
      { "title": "Step Title", "text": "step1.md" }
    ],
    "finish": { "text": "finish.md" }
  },
  "backend": {
    "imageid": "kubernetes-kubeadm-1node"
  }
}

• kubernetes-kubeadm-1node - Single node Kubernetes cluster
• kubernetes-kubeadm-2nodes - Two node Kubernetes cluster
• ubuntu - Plain Ubuntu environment

When creating new scenarios:

1. Create a new directory under killercoda/
2. Add index.json with scenario metadata
3. Add markdown files for each step
4. Use {{exec}} suffix for executable code blocks
5. Test locally using Killercoda's preview feature

```bash
kubectl get pods
```{{exec}}

This renders as a clickable command that users can execute.
